CARVING-MACHINE.

sPEcIrrcA'rIoN forming part of Letters, Patent No. 470,659, dated March 15, 1892.

.Application filed March 27, 1891.

VTo a/ZZ nih/om it vmay concern.-

Be it known that I, JOHN E. BRTELMAIEE, of St. Francis, in the county of Milwaukee and State of Visconsin, have invented a new and useful Improvement in Carving-Machines, of

.which the following is a description, reference mechanism, which will be hereinafter de` scribed and claimed.

In the drawings, Figure 1 is a front elevation of the complete machine. Fig. 2 is a side elevation of the machine as seen from the left in Fig. l. Fig. 3 is a transverse section of the frame-and plan view of the mechanism looking downwardly, as taken on line 3 3 of Fig. 1, a part being broken away to show interior construction. Fig. 4 is a transverse vertical'section of a portion of the machine taken on line 4 4 of. Fig: 3j Fig. 5 is an elevation of a fragment of the machine, parts being broken away and shown in section for better illustration.

The stationary frame A is of suitable form to support the operative machinery. Adriving-shaft B has its bearings in the frame and is provided witha belt-pulley B. Two rotatable tables C of the same size are supported revolubly on the bases D by pivot-pins D', fixed in the tables centrally, which pins are loose in bearings therefor in the bases D. The

bases are fixed on 'the sill 10 of the movable frame. The tables are each provided with a worm-gear in its periphery,which meshes with a corresponding worm E on a shaft E', having its bearings in brackets fixed to the posts 11. of the movable frame. The shaft E' is provided with a fixed pulley, and a belt F running thereon runs also on a pulley7 fixed on a shaft F', having its bearings in the frame. The shaft F' is geared to the driving-shaft B through the pinion G, loose on the shaft B,

but arranged to be clutched thereto by the l or tracer a cross-head or frame L travels vertically in ways L' therefor in the frame, the

cross-head or vertically-moving frame L being carried on vertical screws M, having their bearings in the frame, which screws are connected operatively by the shaft M' and the pinions thereon and are driven by the belt N, running on a pulley on the shaft N', which gears releasably with one of the pinions Ov on sleeve X, splined on one of the screws M. ,The sleeve X is shiftable on the screw M by means of the lever-handle X', pivoted on the frame, and thereby the screws M are capable of being rotated in either direction,

thus providing for raising or lowering the frame L, as4 desired. The belt N runs on a pulley' ontthe shaft N and on a pulley loose l on shaft B, which pulleyy is arranged to be clutched revolubly thereto by a clutch-collar O, splined on the shaft B vand adapted to be shifted into and out of engagement with the belt-pulley by means of a lever-handleO', pivoted on the frame. A rocking bar or frame P is pivoted at its ends in the cross-head L by means of screws Q, turning through parts of thecross-head into bearings therefor in the ends of the bar or frame. The screws Q are locked in position by jam-nuts Q'. The frame P is pivoted and tiltable on the screws Q. A swinging latch R, hinged on the cross-head, engages pins on the frame P and locks it against rocking or rotating when not in use. v A tool-holding frame S, located in the rocking bar or frame P, is supported and travels on wheels S', axled in the lower part of the frame P, and is supported and held in position, movable endwise, against tilting in the IOO frame Pby means of the screws T, which turn through the frame P into grooves therefor in the frame S. A tool -holding spindle U is splined in a sleeve or collar U,so as to have endwise movement therein, and the collar U' has its bearings revolubly in the frame S. The spindle U projects outwardly in front of the rocking frame P, and a guide or tracer V, corresponding in size and form with the spindle U and the tool therein, is supported, movable endwise,transversely in the frame S, and the spindle U and the tracerV are connected together by a cross-branch cross-barrhandle V', in which the spindle is revoluble, being held against endwise movement in the handleV by means of collars on the spindle on both sides of the branching handle. The spindle U and tracer V are at a distance apart and are located, respectively,in front of the material to be carved and the pattern, and the spindle and tracer move concurrently and alike toward and from the material and pattern, respectively, and in vertical and lateral directions.

A cable or belt IV, running on a pulleyB" on the driving-shaft B, runs also on the pulley U", fixed on the spindle U, and for the holding' it taut as the spindle travels with the frame L toward and from the driving-shaft B one leg of the belt runs over pulleys W', axled on the frame, and carries thereon a weight supported on a movable sheave IV", about which the cable runs.

Anti-friction rollers or wheels Y are looseaxled on fixed rods on the frame P on both sides of the cable NV to guard and bear against it under great rocking movement of the frame P. Corresponding anti-friction rollers or wheels Y' are loose-axled on rods supported on the frame A and are adapted to guide'and steady the cable WV where it passes that portion of the frame.

A counterpoise Z, hung on an arm projecting from the frameP inwardly, serves to some extent to balance the cross-bar handle V and adjacent parts ot the mechanism.

The cutting-tool Z', secured removably in the spindle U, is adapted to'cut or rout the material K' to a depth land in the form followed and permitted by the tracer V following the surface of the pattern K.

The movable material and pattern-holding frame consisting of the sill 10, the posts 11, and the cross-beams 12 and 13, in which the spindles I are supported, is adapted to be moved laterally by means of the screws 14, which have bearings revolubly in the frame A and turn by their screw-thread through the posts 11. The screws are rotated by a crankwrench 15. By this construction the mateterial and pattern holding frame, with the mechanism and pattern and material supported thereon, are movable laterally toward Vand from the frame L .and the cutting-tool and tracer supported thereon.

The machine -is operated as follows: A pattern is placed on the table C in front of the tracer V and the material to be carved is placed on the other table C in front of the cutting-tool Z', and both the pattern and material are centered and held revolubly in position by the spindles I turned against them. The pattern and material are moved toward or from the cutting-tool and tracer by rotating the screws 14n, thus moving the materialholding f rame toward or from the cutting-tool and tracer. The pattern and material are rotated, so as to bring all portions thereof in front of the tracer and cutting-tool, respectively, by rotating the shaft E', whereby the tables supporting the material and the pattern are rotated horizontally. The tracer and tool-carrying frame L are raised and lowered to a desired position in front of the pattern and material by rotating the screws M by the action of the belt N, running on the drivingshaft and on a pulley on the shaft N', connected operatively to one ot' the screws M. The cutting-tool and tracer are moved laterally to desired positions by shifting the toolholding frame Sin the rocking frame P, journaled in the frame L. The tracer and cut- Iting-tool being thus brought to the desired position vertically and horizontally in front of and near to the pattern and material are held up to their work by the operator taking hold of the bar-handle V' and pushing the tracer and cutting-tool up to their work, the spindle U, in which the cutting-tool is supported,and the tracerVtherefor being splined and having endwise movement in collars U', which cutting-tool collar U is revoluble in bearings therefor in the frame S and is revolved by the belt W running on the pulley U".

f By operating the mechanism in the manner described in a general way the machine is made to reproduce the pattern in all its details.
